Angular FR

A timing and scoring app to enable quick, unofficial results.

Start with FREO, the event only, ligth version.

FR

fleet race

This is a timing and scoring program which computes results on the client.
Originally a Delphi desktop application, it has been rewritten in java, C#, and Silverlight.
The latest version of the project is a Typescript / Angular app.

RG

Rigg

This is special.
A sail boat rig simulation program.
I bought my first own PC because I wanted to write this program.
First version in Delphi 1, 1995. Has seen many platforms.

FC

Federgraph

Relatively new. A 3D function plotter app written for a specific problem.
The project started in 2012 as a Delphi FMX cross platform project,
you can find a recent version of it in the Windows Store.

Angular RG

The 420 rig trim simulation, super light version.

About this static only site

No user data is collected. There is no web form. You cannot log in or post data to federgraph.de.
I have chosen the long term, economy plan for this site.
There is no server side code and no database, just static html files and other static content.
Static content includes client side javascript demo applications built with Angular.

Use the start buttons to download and run a current build of one of my angular applications.
Applications may load static text data files from federgraph.de, but otherwise there is no connection to a server, no advertising, and no tracking.

About Project FR

FR is the big project I have been working on since 2003, and which has been paused between 2011-2017,
and which I revisited in 2018.

A new and impoved Windows desktop version is almost ready,
it works in tandem with the Angular client,
the Mac version will have to be done from scratch in XCode using Swift.
I may end up posting a new and special build to the Windows store in 2019,
and at the same time publish the source on github
so that you can build yourself,
read the source to find out how it works,
and help me with the Mac rewrite.

From here you can access four preview demo versions of the FR Angular app:

Read about service-worker on the Angular site.
The FR service-worker version should be preferred if your browser can use it.
The service-worker technology is used to use cached static resources, so that the application can be used offline.

About store presence

All apps I published between 2012-2017 (RG and FC, mobile / desktop) will be removed from the store.
I plan to continue with the projects, but I can't say if I will build new versions for the store.

The reason is that so far I have done cross-platform builds using Delphi FMX and there are problems with this approach.
It was great initially and it worked, but it is difficult to keep the apps current.
The FC desktop app (Windows) had a price tag and low traffic, the RG desktop app (Mac) is 32 bit only,
the RG and FC Android apps are out of date now and no longer on par with the desktop app.
The FC iOS app was out of date as well, the FC desktop app on Windows has advanced a lot.

So, the real thing has always been to compile the app and run it on the desktop, in the debugger.
A feature reduced native and up to date demo version of FC may make it to the store, but not the real thing.
RG is alive - please get in contact if you purchased a version from the Mac store.
FR is currently hot and I would like to incourage you to have a look.
